ELECTRIC HEATER.

SPECIFICATION forming part of Letters Patent NO. 565,574, dated August 11 1896.

Application filed March 20,1896. Serial No. 584,197. (No model.)

To all whom t may concern:

Be it known that I, RICHARD VAN R. SILL, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Electric Heaters, of which the following is a specification.

This invention relates to electric heaters; and it consists of the new construction and combination of elements for the purpose of generating and radiating heat, substantially as hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure lis a perspective view of a heater embodying my invention, showing a portion of the outer Fig. 2 is a vertical section of one of the heating-pipes, showing the construction and arrangement of same.

A A are vertical tubes or chambers composed of clay o1' other suitable non-conducting material made in pairs by being bent or the said filling. They are held in place by means of disks of lead and are hermetically sealed with plaster-of-paris or other suitable 3o material to exclude air.

The special advantages of this construction are that the upright tubes or chambers, having the electrodes in their lower ends, will always retain the contact of the elec- 35 trodes with the filling by gravity, as the jarring of the heater would cause the filling to press upon the electrodes and thereby preserve their contact, and also being hermetically sealed, air is excluded and the liability 4o of arcing and burning is avoided.

Having described my invention, I claim- The combination of a hermetically-sealed radiator having vertical chambers communieating with each other at their upper ends, 45 a comminuted resistance filling said radiator, and an electrode extending into the lower end of each chamber, and having contact with the resistance material, substantially as described.

RICHARD VAN R. SILL.
